1. For blob data, a design must ensure the data is readable from a secondary region even while the primary region is available, to serve read traffic and improve resilience. Which redundancy option should the architect recommend?
- A. Read-access geo-redundant storage (RA-GRS) or RA-GZRS✓ Correct
- B. Locally redundant storage (LRS)
- C. Zone-redundant storage (ZRS) only
- D. No redundancy
Explanation
RA-GRS (or RA-GZRS) adds read access to the geo-replicated secondary copy, so applications can read from the secondary region even before a failover. LRS (B) is single-datacenter, ZRS (C) has no secondary region to read from, and no redundancy (D) fails the requirement.
